Around two years ago, on 2015-03-29 to be precise, Smack 4.1.0 was tagged and released. A few days ago I've tagged and released Smack 4.2.0 to Maven Central. The 4.2.0 release marks a milestone for Smack, but before I got into the exciting new features, I'd like to thank the various contributors:

I can not remember when Smack had so many contributors. Thanks everyone and keep the contributions coming.

The notable changes to Smack 4.2 include support for DNSSEC (thanks to a previous MiniDNS GSOC project), JIDs as first class citizens by using JXMPP's JID API, and tons of other improvements, new features and bug fixes. You can read more in the Smack 4.2 Readme and Upgrade Guide and the Smack's JIRA release notes.
